Issued latest IPv4 / 8 blocks
As InfoQ predicted last week, the place in IPv4 ended in January 2011. As a result of a request from APNIC (General Registry for Asia and the Pacific) to provide two IPv4 / 8 units, the last five were distributed to the remaining RIRs (according to RIPE-436 policy)
In the IANA IPv4 address space there are, of course, several IP blocks reserved for "future use", but they are unlikely to be released because they are reserved for changes to the protocol. Some of them are in the reserved class E. Since they are used for multicast, do not use them for regular servers; and indeed many routers simply won't let traffic to these addresses.
From a practical point of view, the RIRs have already received all the addresses that they could. APNIC wrote in their last query :
The distribution of IPv4 addresses will continue in each region until they end in each of them. It is likely that the APNIC or ARIN addresses will not remain earlier than the others (for example, AfriNIC or LACNIC). Some pools will be empty by the end of the year, someone can make it to the next.

To speed up the proliferation of IPv6, Google and other companies have proposed World Day for IPv6 on June 8, 2011; You can check in advance if you have IPv6. The transition to a new technology means that the sites will host on both the fourth and sixth versions of the protocol, and the likelihood is high that IPv4 will live for quite some time. For example, if you have a blog on blogger , you can make it available on both IPv4 and IPv6.
Are you ready for IPv6? Does your provider support it, or maybe you have a tunnel through Hurricane Electric or Sixxs ?

We reiterate that IPv6 is the only means by which the Internet can grow and thrive, and we ask everyone involved in the Internet industry to switch to it as soon as possible.
